A moving mechanism relatively moves a machining head that emits a laser beam from an opening of a nozzle with respect to a sheet metal along a surface of the sheet metal to produce a product having a predetermined shape by cutting the sheet metal. A beam vibration/displacement mechanism vibrates or displaces the laser beam with which the sheet metal is irradiated to produce the product while relatively moving the machining head by the moving mechanism. A moving mechanism control section controls the moving mechanism to relatively move the machining head with a first control period. The vibration/displacement control section controls the beam vibration/displacement mechanism to vibrate or displace the laser beam with a second control period shorter than the first control period.

A method of manufacturing a part includes additively manufacturing, with an additive manufacturing machine, at least one wall of the part having a first thickness from powder in a powder bed, and peening, with a peening system, at least a portion of the wall of the part. The peening induces plastic deformation in the portion of the wall. The portion of the wall that is peened has a second thickness less than the first thickness of the wall prior to peening. The second thickness of the portion of the wall may be less than a minimum thickness limit achievable by the additive manufacturing machine.

A robot system includes a work apparatus, a robot, and control circuitry. The work apparatus is configured to move a work module relatively to the work apparatus.

A moving mechanism relatively moves a machining head emitting a laser beam, with respect to a sheet metal along a surface of the sheet metal. A beam vibrating mechanism vibrates the laser beam for irradiation on the sheet metal, while the machining head is relatively moved by the moving mechanism. A machining condition setting section sets pattern selection information to select a vibration pattern of the laser beam by the beam vibrating mechanism, and a parameter to determine a vibrating way in the vibration pattern, in accordance with machining conditions specified for each machining command to machine the sheet metal in a machining program generated to machine the sheet metal, and including a machining velocity of the sheet metal associated with relative movement of the machining head by the moving mechanism.

In a method for determining a deviation of a spatial orientation of a beam axis (S) of a beam processing machine from a spatial nominal orientation (S0) of the beam axis (S), contour sections (KA1, KB2) are cut with a processing beam into a test workpiece from two sides of the workpiece. The contour sections (KA1, KB2) extend parallel to a nominal orientation of a rotation axis (B, C), where the rotation axis is to be calibrated. The contour sections (KA1, KA2) are probed from one side of the test workpiece by a measuring device for determining the spatial position of the contour sections (KA1, KB1). Deviation of the spatial orientation of the beam axis (S) of the beam processing machine from the spatial nominal orientation (S0) is determined based on the spatial positions of the contour sections (KA1, KB1).

A 3D laser machining system comprises: a move state simulation unit that simulates a move state of a machining head using 3D CAD data about a workpiece containing material information defining thermophysical properties and 3D CAD data about a machining head under a condition of moving the machining head relative to the workpiece while the machining head is maintained at a predetermined angle a predetermined distance along a machining line in virtual space; a thermal fluid simulation unit that conducts non-stationary thermal fluid simulation for obtaining a temperature distribution in a region covering the workpiece to be changed by the move of the machining head outputting a laser beam; and a machining condition setting unit that sets a laser machining condition containing a relative move condition for the machining head and a laser beam output condition before laser machining on the basis of results of the simulations.

A laser reflow apparatus capable of reducing tact time for a single bonding object, and accelerating an overall bonding process for all of a plurality of bonding objects is provided. The laser reflow apparatus comprises a bonding object transfer unit including a stage, a laser emission unit, a beam transmission plate, and a beam transmission plate transfer unit.

A control device controls a beam vibrating mechanism to vibrate a laser beam in a C-shaped vibration pattern in which a beam spot is moved from a first irradiation position at a front end in a cutting advancing direction to a second irradiation position at a rear side and displaced in an orthogonal direction to the cutting advancing direction, and is moved from the second irradiation position to a third irradiation position at a front end and displaced in the orthogonal direction to the cutting advancing direction, and movement from the first irradiation position to the third irradiation position via the second irradiation position, and movement from the third irradiation position to the first irradiation position via the second irradiation position are repeated. The control device performs control to cut the sheet metal by causing beam spots in the first to third irradiation positions to overlap one another.
